METALLIC ROOFlNG.

SPECIFICATION forming part of Letters Patent No. 412,043, dated October 1, 1889. Application filed July 11, 1889 Serial No. 317,212. (No model.)

To all 1071,0122, it may concern.-

Be it known that I, LONGLEY LEWIS SAGEN- DoRPH, a citizen of the United States, residing at Cincinnati, in the county of Hamilton,

State of Ohio, have invented certain new and useful Improvements in Metallic Roofing Sheets, of which the following is a specifica tion, reference being had to the accompanying drawings, forming a part thereof.

The object of my invention is to so construct the side flanges of a roofing-sheet as that the inturned hooked flange of one sheet will engage with inturned spurs cut from the outward-turned flange on the adjacent sheet, as will more fully hereinafter appear.

In the accompanying drawings, Figure 1 is a plan View of the end portion of a roofingsheet before the side interlocking flanges are bent, showing the position of the spurs cutin one of said flanges; and Fig. 2 is a perspective view of one end of the sheet after the side flanges are bent to position. Fig. 3 is a view the reverse of that shown in Fig. 2, showin g one of the retainingcleats in position; and Fig. a is a vertical section on an enlarged scale through the flange and cleat shown in Fig. 3. Fig. 5 is a perspective view of the end portions of two sheets of roofing, said view showing the left-hand sheet in the act of being slipped to place over the hooked flange of the other sheet. Fig. 6 is a perspective view of the standing seam produced by the union of my improved sheets. Fig. 7 is a vertical crosssection through the side flanges and one of the interlocking spurs before being clamped or pressed to place, and Fig. Sis a view showing said flanges and spur locked to place. Fig. 9 is a vertical cross-section through the flanges,cleat, and interlocking spur in a locked position.

My invention consists in forming inwardprojecting spurs a. from the downward projection of flange b on one side of the roofingsheet, the flange b on the other side of the sheet being bent and hooked inward in the same direction that flange b is bent. The spurs a are formed by cutting the metal at three sides thereof, and forcing the metal between said cuts inward, as shown.

My improved rooflng sheets are applied and A suitable cleat O, bent connected as follows:

to conform to flange I), is hooked over the latter and nailed to the sheeting, as shown. This cleatserves to anchor one side of the sheet to the sheeting. Having properly secured the first row of roofing sheets to place, the flange b of the adjacent sheet is slipped over the flange I), and in such a manner that said latter flange will slide between the spurs a and the inner face of flange Z), as is more clearly shown in Figs. 5, 6, and '7. Having slipped the overlapping sheet to place, the flanges, spurs, and cleats are firmly compressed and locked, as shown, by a suitable clampingtool. The spurs a serve to retain the'over lapping sheet firmly in contact with the flange of the lower sheet. Each successive row of roofing-sheets is applied and connected in the manner just described.

The advantages of my improved roofingshect are apparent. By forming the interlocking spurs in the one side flange to engage the flange of the adjacent sheet a standing seam is provided which is perfectly watertight and free from any overlapping cleats, thus saving the material usually employed in the overlapping cleats to retain the top sheet in contact with the lower sheet, as the spurs cut from the outside flange will. retain said top sheet in position. The roof is ready of application, presents a neatappearance, is durable, and will admit of all requisite expansion and contraction.

hat I claim as new, and desire to secure by Letters Patent, is-

1. A sheet of metal roofing provided on one side with an outward-projecting flange having inward-projectin g spurs on its downward extension, the opposite side of said sheet hav ing an inturned flange, substantially as set forth.

2. In a metal roof, the combination of inturned flange b, cleat O, and the outward overlapping flange Z2, the cleat C fitting over flange l2 and nailed to the sheeting, said flange b engaging between the spurs a and the inner face of flange b, substantially as set forth.
